A stock aircraft called Wyvern Retriever + Dirk. Built with 323 of the finest parts, its root part is mk3Cockpit.Shuttle.
Built in the SPH in KSP version 1.3.0.
- Type: SPH
- Class: ship
- Part Count: 323
- Pure Stock
The Retriever variant of the Wyvern is outfitted with a retractable cargo grapple for cleaning up debris after a flight. She also has a Vernor based RCS for fine hover control. I decided on the Dirk as a torture test for the grapple. The Dirk weighs ~30 tons.
Rotor/bearing assembly redesigned to increase performance, durability, and reliability.
GVWR is now ~130tons. (properly balanced)
Cargo grapple now docks in both positions allowing control of the Klaw while deployed without the need to change craft.
Added parking brake allowing for timewarp, quicksaves, and craft switching while the craft is landed.
Flight manual at page bottom.
The Dirk is designed to fit in a Mk3 cargo bay and is a capable performer. She’s a lot of fun to blast around Booster Bay in. She also has landing gear to allow her to self-launch.
I’d call that a succesful test!
- Ensure landing gear (rotor deflection compensators) are stowed (note: landing gear should always be stowed before docking/undocking any part of the craft)
- Throttle up and stage to release the rotors and engage blowers.
- AG 1 toggles heavy lift mode (required for lift off with GVW above ~90 tons) Note: Thrust asymmetry between rotors sometimes develops during lift off resulting in a hard roll. If this occurs, set the craft down, brake the rotors and begin again. This will not self-correct.
- Transition to forward flight by pressing AG 2 to toggle forward flight engines. When the craft reaches ~20m/s disengage heavy lift mode (if currently in use), and deploy landing gear. The craft will have a tendency to pull up hard during transition to forward flight. Keep the nose down. Flight pattern should stabilize around 100-120m/s depending on GVW and COM.
- Flaps (AG 5) can be helpful during forward flight transition and for maintaining altitude with heavy loads. Likewise, it may be necessary to use heavy lift mode (AG 1) during forward flight to maintain altitude. Either engage heavy lift mode and throttle down until the flight pattern becomes stable, or pulse heavy lift mode on and off to maintain altitude.
- It is recommended to use roll/pitch to make turns. Yaw inputs have a tendency to introduce heavy counter-roll (which can confuse SAS).
- AG 6 toggles thrust reversers on forward flight engines. This can be useful when approaching an LZ.
- Cargo grapple should only be operated during hover with landing gear stowed. Once cargo is secured to the grapple, it is safe to transition to forward flight (use caution).
- AG 3 toggles grapple between stowed and deployed positions (note: anytime docking occurs, throttle will revert to zero, be prepared to correct throttle after changing position of the grapple).
- AG 4 toggles arm/disarm on the Klaw.
- After landing the craft, use brakes on the landing gear to slow rotor spin.
- Once rotors have slowed sufficiently, stow landing gear.
- AG 0 toggles the parking brake. Once set, it is safe to change craft, quicksave, timewarp, etc.
- Upon returning, simply toggle the parking brake off (AG 0), and operate as usual.
Do you really want to downvote this?
Don't forget, people build craft at all skill levels, just 'cos something is 'newbish' doesn't mean it needs hatin'.
It will cost you 5 of your own points to downvote
